'Location'(geolocation) support in OS versions - iphone

Is 'Location'(geolocation) native api supported in all iphnoe os versions from iphone 2.o to ios 4+ ? Is there any documentation to get the list of all API's and the supporting versions ?

Sure, its called core Location Framework:

which google map version for ios 5

I am using mac lion os 10.7.4, i want to integrate my application with google map. thus, i read the official google map guide, then i got this exception google map on iphone exception . as a result, i discoverd that i have to use another version of google map in order to support ios 5 , but unfortunately i am not able to know which version is.
any help would be appreciated
versions smaller than 1.5 supports iOS down to to 5.1 but they aren't that reliable i experienced.
with a not supported HACK you can support 5.0 :D but that is NOT a supported config:
#pragma mark - workaround
//make it work on 5.0 :D
NSString* const NSURLIsExcludedFromBackupKey = #"NSURLIsExcludedFromBackupKey";
